BC is a chord with centre O. A is a point on an arc BC . Prove that: ∠BAC+∠OBC= 90 , if A  is the point on the major arc.

BC is a chord with centre O. A is a point on an arc BC as shown in Figure.Prove that: /_BAC+/_OBC=90^(0), if A is the point on the major arc.

BC is a chord with centre O. A is a point on an arc BC as shown in Figure.Prove that: /_BAC-/_OBC=90^(0), if A is the point on the minor arc

In the figure,BC is a chord of the circle with centre o and A is a point on the minor are BC. Then /_ABC-/_OBC is equal to
